The mobile wireless communication device (101a-c) is configured to be part of a cluster of mobile wireless communication devices managed on the basis of a clustering protocol, wherein the clustering protocol is configured to select one of the mobile wireless communication devices (101a-c) of the cluster of mobile wireless communication devices to be a cluster head for representing the cluster of mobile wireless communication devices. The mobile wireless communication devices (101a-c) of the cluster of mobile wireless communication devices are either in a network-connected mode or a network-idle mode relative to the wireless communication network. ## Claims ### Claim 1 A mobile wireless communication device in a communication system, comprising a processor that are capable of executing program instructions stored in a memory, wherein, by executing the program instructions, the program instructions cause the device to: select one of the mobile wireless communication devices of a cluster of mobile wireless communication devices, including the mobile wireless communication device itself, being in the network-connected mode as a cluster rapporteur for communicating with the location management server; and send cluster location management information to the location management server, wherein the cluster location management information comprises information about a location of the cluster head and/or information about respective locations of the mobile wireless communication devices of the cluster of mobile wireless communication devices. ### Claim 2 (depends on 1) The mobile wireless communication device of claim 1, wherein the processor is further configured to determine the frequency or the content of the cluster location management information or the events that trigger the sending of cluster location management information to the location management server. ### Claim 3 (depends on 1) The mobile wireless communication device of claim 1, wherein the cluster location management information further comprises an identifier of the cluster of mobile wireless communication devices, location information about the cluster head, information about the velocity of the cluster head, a list pairing an identifier of a wireless mobile communication device of the cluster of mobile wireless communication devices, such as an IMSI, with an identifier of a cell of the wireless communication network, and/or the coverage area of the cluster of mobile wireless communication devices. ### Claim 4 (depends on 1) The mobile wireless communication device of claim 1, wherein the processor is further configured to send cluster location management information the location management server, each time another mobile wireless communication device joins the cluster of mobile wireless communication devices, another mobile wireless communication device leaves the cluster of mobile wireless communication devices and/or the cluster of mobile wireless communication devices is changed in a different way. ### Claim 5 (depends on 1) The mobile wireless communication device of claim 1, wherein the processor is further configured to communicate with the other mobile wireless communication devices of the cluster of mobile wireless communication devices over an intra-cluster communication channel. ### Claim 6 A method for transmitting data in a wireless communication network, comprising: selecting one of the mobile wireless communication devices of a cluster of mobile wireless communication devices, including the mobile wireless communication device itself, being in the network-connected mode as a cluster rapporteur for communicating with the location management server; and sending cluster location management information to the location management server, wherein the cluster location management information comprises information about a location of the cluster head and/or information about respective locations of the mobile wireless communication devices of the cluster of mobile wireless communication devices. ### Claim 7 (depends on 6) The method according to claim 6, further comprising: determining the frequency or the content of the cluster location management information or the events that trigger the sending of cluster location management information to the location management server. ### Claim 8 (depends on 6) The method according to claim 6, wherein the cluster location management information further comprises an identifier of the cluster of mobile wireless communication devices, location information about the cluster head, information about the velocity of the cluster head, a list pairing an identifier of a wireless mobile communication device of the cluster of mobile wireless communication devices, such as an IMSI, with an identifier of a cell of the wireless communication network, and/or the coverage area of the cluster of mobile wireless communication devices. ### Claim 9 (depends on 6) The method according to claim 6, further comprising: sending cluster location management information the location management server, each time another mobile wireless communication device joins the cluster of mobile wireless communication devices, another mobile wireless communication device leaves the cluster of mobile wireless communication devices and/or the cluster of mobile wireless communication devices is changed in a different way. ### Claim 10 (depends on 6) The method according to claim 6, further comprising: communicating with the other mobile wireless communication devices of the cluster of mobile wireless communication devices over an intra-cluster communication channel.
